8€ (abt 9$) for Italy, 10€ (abt 11$) for UE and USA, 12€ (about 13,5$) for the rest of the world. Shipping costs to the customers. At the end of the campaign we will contact you to know your address and your size. As you can see on Kickstarter the first deliveries are due by the end of July. More detailed info on the delivery times will be provided in the future.
The details will be collected once the Kickstarter campaign finishes. However, due to the currently limited choice among different models, we may be able to start the first production bacthes before the campaign ends, thus reducing delivery time.
